arrays - 从数据库中收集所有记录并检查是否存在

Question

我在 Yii 框架中工作，我有一个问题。我有一张带便利设施的桌子，我想找到所有东西。

$amenities = RoomTypeAmenity::model()->findAll(); 这个命令工作正常。

然后我想找到这个房间有什么设施，然后输入 $amenities_room = RoomTypeAmenity::model()->with('idRoomTypeAmenity')->findAll(); 这个命令工作正常。但是当打印设施时，我想检查现有的设施。

    foreach ($amenities as $amenity) { ?>
        <input type="checkbox" class="css-checkbox" id="facility_<?php echo $amenity->id_room_type_amenity; ?>">
        <label class="css-label" for="facility_<?php echo $amenity->id_room_type_amenity; ?>"><?php echo $amenity->name; ?></label>

        <?php  }?>

Answer 1

使用if else条件里面for-loop。检查当前 amenity_room 是否存在当前 amenity。如果退出，checked则checkbox.

foreach ($amenities as $amenity) { ?>
     if($amenity->id_room_type_amenity!=null){
         <input type="checkbox" class="css-checkbox" id="facility_<?php echo $amenity->id_room_type_amenity; ?>" checked>
         <label class="css-label" for="facility_<?php echo $amenity->id_room_type_amenity; ?>"><?php echo $amenity->name; ?></label>
     } else {
         <input type="checkbox" class="css-checkbox" id="facility_<?php echo $amenity->id_room_type_amenity; ?>">
         <label class="css-label" for="facility_<?php echo $amenity->id_room_type_amenity; ?>"><?php echo $amenity->name; ?></label>
     }

<?php  }?>

希望这可以帮助！
